Wringing apparatus for mops includes a roller, a fixed reaction member against which the mop fringe is positioned and means for bringing the roller from an inoperative position to one in which it bears against the fringe and then to move the roller across the fringe hence expelling liquid. As shown in Fig. 1 the apparatus may comprise a framework 1, 2, 3 carrying two open topped tanks 6 and 7 which respectively serve to collect waste liquid from the mop and contain cleansing liquid. The actuating mechanism for roller 9 comprises a series of links 16, 18 and 21 so arranged that when arm 13 is in the position shown in dotted lines the roller is in its unoperative position and movement of arm 13 by handle 11 to position shown in full causes the roller to bear down on reaction plate 8. Further downward movement of handle 13 causes the roller to roll across the plate and hence expel liquid from the mop fringe when it is placed against the surface of the plate. The mop head is held in position by support 25.
